This is truly an epoch making event.BBC News confirms that Voyager one which was launched 36 years ago to study the outer planets Jupiter,Saturn,Uranus and Neptune;has gone beyond it's original task and entered inter-stellar space.It is believed that this happened around 25th August 2012.It is so far from earth that signals sent by it take 17 hrs to reach earth.
This is the first man made object to leave the solar system.Although it is now out of the solar system,it can still feel the sun's pull.It will take nearly 40,000 years to approach another star even though it is moving at a speed of 45km/s and it will orbit around the center of our galaxy with all it's stars for billions of years.In 1990, when Voyager looked back to earth it was seen as a blue dot
In terms of size earth may not be so earth-shaking,but look at what a stupendous achievement earthlings have made. Marvelous!
